About Us
Profile
Sovereign has been dedicated to the field of water proofing since 1972. Upon realizing the severity of the problems associated with water ingress, Sovereign embarked on a research programme which resulted in lodging its first patents in 1974.
Uncontrolled penetration or water leakage into or through building structures, underground and mining excavations, dam walls, foundations and the like can be one of the most annoying, difficult, dangerous and costly problems faced by engineers, owners and operators.
Sovereign specializes in the sealing of water with a high flow rate / volume and leaks with a rate of 9900 Lt per minute at 180 P.S.I, have been successfully sealed in underground mines.
Sovereign’s sealing technology also excels in conditions where the water pressure is very high and leaks with pressures of 2465 P.S.I. at a flow rate of 850 Lt per minute have been successfully sealed.
Sovereign is qualified to report to the Mining and Civil Construction industries.
back to topDevelopment - Our Future
Sovereign’s technology is not limited to water sealing only - we are spearheading the sealing of compressed gasses and air in large structures never achieved before. Sovereign is piloting experimental projects in the USA with partners in the energy resources industry where our sealing technology are continuously tested in alternative renewable green energy trials, doing our best to help face the global energy crises and saving the world for our children.
Our grouts were also further developed to be used in briny conditions and recent tests were successfully completed in North American salt mines where it was demonstrated that salt mines can also benefit by our flexible and impermeable grouts.
Trials are also been conducted using Sovereign’s sealing technology for use in the oil and gas industries in off shore applications in the Gulf of Mexico and the Middle East. Our research team is continuously pursuing the technology of tomorrow as well as creating the ultimate seal.
